Kudos

Description

Kudos, as seen on the svbtle.com blogging network, are an unobtrusive and playful
way for your readers to show their appreciation. To give kudos for a post the visitor
simply hovers the Kudo-Button: A small animation starts for as long as the visitor does leave his cursor on the Kudo. When the animation is finished and the Kudo-Button is filled the count goes up by one. By clicking the then filled button the visitor can take his Kudo off the post again.
